Housewardans with Sunday! Yuu :

Riddle

He appreciates Sunday! Yuu’s Leadership and Knowledge and respects Sunday Yuu for mostly following the rules

Sunday! Yuu disargees with a decent amount of the rules due to how strict the punishment is for the most mundane things and dislikes the lack of freedom and authority that comes along but still follows the rules nonetheless

They understand it’s hypocritical of them to say the part about freedom and authority

Sunday! Yuu also respects Riddle for his leadership and dedication but disargees with the strictness of it all.

During book one, Sunday! Yuu has to confront their own childhood along with Riddle’s.

They both were manipulated and raised by parental figures in thier lives that forced down a harmful philosophy into them for their own gain

Like when Trey tells them about riddles mom Sunday! Yuu can picture Mr Gopher Wood.

And during the overbolt section with the flashbacks,Sunday! Yuu is fighting every urge for tears not to fall out of their eyes when seeing riddle’s childhood and seeing their’s and robin’s childhood along with it

Sunday! Yuu ends up sobbing with riddle while hugging him. They miss robin so much

After all that,Sunday! Yuu would try to help riddle be less strict on his dormmates and help him lead heartslabyul

Leona

Leona thought Sunday! Yuu was a stuck up before book 2

Leona also could tell something was off with Sunday ! Yuu so he was a bit wary of them

Sunday! Yuu saw him as a lazy and unfit leader before book 2 as well

With Sunday! Yuu kinda reminding him of Malleus yea they did not like each other

During book 2,Leona kinda respected Sunday! Yuu’s intelligence to come up with that plan but that also came with a scoopful of jealousy

When Sunday! Yuu saw the flashback sequence,They did sympathize leona but also saw it as leona giving up an already high position because he couldn’t get a higher one.

So in comparison to riddles heartfelt comfort,Sunday! Yuu actually had a debate (more like lecture) with leona about how being in second place is still in the leaderboard and how leona could actually make a difference if he tried

After all that,Leona respects Sunday! Yuu more but they still don’t really like each other.

Azul

Nuh uh, Sunday! Yuu doesnt like him from the start. Being the head of the oak family in penacony,they have met plenty of shady business people most from the ipc

On that note, Azul reminds Sunday! Yuu wayyyy too much of ipc Stoneheart Jade.Granting wishes for a price of equal value that ends up the price being way worse than the wish? Sunday! Yuu knows what azul wants and will refuse to give it under all circumstances.

Doesnt help that one of the tweels is named Jade too Sunday! Yuu almost had a heart attack after hearing his name lol

Azul is immensely curious about Sunday! Yuu and their halovain nature and their power of the harmony.Always sending the tweels to spy on Sunday! Yuu,but due to Sunday! Yuu’s experience with this kind of stuff they will always find their way out.

During book 3,Sunday! Yuu was scolding the firstyears nonstop about signing a contract with him. And was also pretty shocked about the merpeople and their forms.

During the flashback sequence, Sunday! Yuu would sympathize with azul but still would not forgive him for his actions and same with leona would have a lecture with him about how if others hurt you that doesnt justify you hurting others for your gain.

After all that, Sunday! Yuu still doesnt like azul but azul still respects and admires Sunday! Yuu’s power and ability.

Kalim

Kalim really likes Sunday! Yuu.Coming from the land of festivities, Sunday! Yuu’s sure knows how to organize a spectacular party.

Sunday! Yuu helps organize Kalims many partys and keeps him in check to the relief of Jamil

Sunday! Yuu finds Kalim quite enjoyable and sweet though pretty careless.

They also regularly checks out the Light Music Club and helps them with songs as they have experience with music due to working with robin

They sometimes sing there with the power of harmony but it took a long time to convince them to even try singing It brought back too many memories

I dont really have a lot for kalim Sorry! Because the overbolt was mainly for Jamil

Overall, Kailm and Sunday! Yuu like eachother pleasantly.

Vil

Vil likes Sunday! Yuu a fair bit. Sunday! Yuu has experience in the showbiz world from robin and understands alot of celebrity culture, beauty, social media etc so Vil sees Sunday! Yuu as a knowledgeable individual and respects them for that.

Sunday! Yuu respects Vil for his effort,determination and drive and often help him with management issues and other stuff of the like

During book 5,The first years begged for Sunday! Yuu to join VDC and eventually they caved.They actually got in as a performer due to their voice and experience with the field but they also became the producer of the competition on their own request.

Vil commitment to routine with his skincare, food, makeup reminded him much of himself and robin’s routine. Almost everything reminded them of robin, they miss her more than anything else

And when Sunday! Yuu saw Neige Le Blanc,they felt the urge to protect and hug him.The soft angelic glow and the sweet melodic voice was too much for Sunday! Yuu to handle.They were already having mental issues with everything reminding them of robin and with neige being very similar to robin Sunday! Yuu was having a mental breakdown ngl

And instead of Rook saving neige, Sunday! Yuu was the one to smack the apple juice out of neiges hand.The brotherly urge to protect was too strong even though it didnt really matter to Sunday! Yuu if Neige died or not.

During the flashback sequence ,Sunday! Yuu was dead slient,they were emotional but not as emotional with riddle’s.It still hit too close to home with all the acting and celebrity world.

This time Sunday! Yuu just had a mature conversation with vil about his jealousy and pride.

Idia

Idia thought Sunday! Yuu was an SSR morally grey villain ikemen in a video game.

Sunday! Yuu didnt even know who he was other than housewarden of Ignihyde and a social recluse.Though they’d often use Ignihyde technology due to that being the closest to the technology back in their world

But during Book 6, ooooh boy was it depressing,horrifying and dangerous all in a mechanical package.

The overbolt was insanly tough They almost exhausted all their energy to support the other housewardens.

And the flashback was chilling, The incident of ortho’s death, young idia’s wails and crys left Sunday! Yuu feeling horribly terrified,sortowful and empty.

They has experienced the loss of a family member since a young age too, and almost lost robin in penacony. What if like ortho, Robin had died when they were young? Would they be like idia today the thought was too horrible.

Sunday! Yuu didnt even say anything to idia afterwards but tears did fall from their face.

Malleus

Malleus is horribly down bad for Sunday! Yuu (platonic or romantic you decide).He is utterly curious about their halovain background, Malleus had actually thought Sunday! Yuu was a fae or an angel when he first met them.

Sunday! Yuu is also pretty interested in malleus and the mystery of who he is.As I said in the beginning they have some large similarities and they’d definitely get along.

They’d both rant to eachother about alot and theyd both listen to eachother and argee with eachother.

Malleus felt a real friend to Sunday! Yuu someone who understood them and their similarities often made them both seem seen by the other

Sunday! Yuu probably wouldn’t call Malleus tsunotarou, I’d imagine it’d be something like Mr draco/drago or something of the like
